5. Suppose you invested PHP 25,000 at a simple interest at a rate of 2.5%, how much will be your investment after
10 years? a. PHP 43,750.00
C.PHP 45,730.00
b. PHP 31,250.00
d. PHP 47,350
Answer:
b. PHP 31,250.00
Step-by-step explanation:
Simple interest = principal × rate × time
Principal = PHP 25,000
Rate = 2.5%
Time = 10 years
Simple interest = principal × rate × time
= PHP 25,000 × 2.5% × 10
= 25,000 × 0.025 × 10
= 6,250
Simple interest = PHP 6,250
Investment after 10 years = principal + simple interest
= PHP 25,000 + PHP 6,250
= PHP 31,250
Investment after 10 years = PHP 31,250

The equivalent value of the expressions are solved by the exponents
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
A = 25ˣ
On simplifying , we get
A = ( 5 . 5 )ˣ
A = ( 25 )ˣ
And , A = 5ˣ . 5ˣ
From the laws of exponents , we get
mᵃ×mᵇ = mᵃ⁺ᵇ
A = 5²ˣ
A = 25ˣ
Hence , the expressions are ( 5 . 5 )ˣ = 5²ˣ = 5ˣ . 5ˣ = 25ˣ

What's the largest fraction in each group? a. 5⁄6 and 29⁄36 b. 5⁄12 and 3⁄8 c. 2⁄5 and 19⁄45 d. 5⁄7, 13⁄14, and 19⁄21
Solution :
We have to find the largest fraction in each group.
a). [tex]$\frac{5}{6}$[/tex] and [tex]$\frac{29}{36}$[/tex]
[tex]$\frac{5}{6}$[/tex] → when we divide the number 5 with 6, we get 0.833
[tex]$\frac{29}{36}$[/tex] → when we divide 29 by 36, we get the value 0.805
Therefore, in this group, [tex]$\frac{5}{6}$[/tex] is the largest fraction.
b). [tex]$\frac{5}{12}$[/tex] and [tex]$\frac{3}{8}$[/tex]
[tex]$\frac{5}{12}$[/tex] → when we divide the number 5 with 12, we get 0.416
[tex]$\frac{3}{8}$[/tex] → when we divide 3 by 8, we get the value 0.375
Therefore, in this group, [tex]$\frac{5}{12}$[/tex] is the largest fraction.
c). [tex]$\frac{2}{5}$[/tex] and [tex]$\frac{19}{45}$[/tex]
[tex]$\frac{2}{5}$[/tex] → when we divide the number 2 with 5, we get 0.40
[tex]$\frac{19}{45}$[/tex] → when we divide 19 by 45, we get the value 0.42
Therefore, in this group, [tex]$\frac{19}{45}$[/tex] is the largest fraction.
d). [tex]$\frac{5}{7}$[/tex], [tex]$\frac{13}{14}$[/tex] and [tex]$\frac{19}{21}$[/tex]
[tex]$\frac{5}{7}$[/tex] → when we divide the number 5 with 7, we get 0.714
[tex]$\frac{13}{14}$[/tex] → when we divide 13 by 14, we get the value 0.928
[tex]$\frac{19}{21}$[/tex] → when we divide 19 by 21, we get the value 0.904
Therefore, in this group, [tex]$\frac{13}{14}$[/tex] is the largest fraction.

Write an equivalent expression. -2(7+5g)
Answer:
-2(7) + -2(5g)
Step-by-step explanation:
Using the distributive property we can confirm that:
-2(7) + -2(5g) = -2(7+5g)
Answer:
−14−10g
Step-by-step explanation:
First, solve the product:
-2 ⋅ 7 - 2 ⋅ 5g
Multiply -2 times 7 to -14.
So, the equivalent expression would be:
-14 - 2 ⋅ 5g = -14 - 10g
-14 - 10g

Write an explicit formula for the nth term of this sequence:
6, 11, 16, 21, . . .
1. an=5n+11
2. an=5n+1
3. an=21-5n
4. an=6n+1
Answer:
2)an = 5n + 1
Step-by-step explanation:
This is an arithmetic series.
6 , 11 , 16, 21 ,.....
First term = [tex]a_{1}[/tex] = 6
Common difference = d = second term - first term
= 11 - 6 = 5
nth term = [tex]a_{1}+(n-1)*d[/tex]
= 6 + (n - 1) * 5
= 6 + n * 5 - 1*5
= 6 +5n - 5
= 6 - 5 + 5n
= 1 + 5n

8.6 x10^-9 in standard form
-9 in power means that the value is in fractional and the 10 base is multipied 9 times and put it on denominator.
8.6 = 86 x 10^-1
Let's multiply :
86 x 10^-1 x 10^-9
= 86 x 10^-10
= 86/10000000000
=0,0000000086
Note : if you don't know about how 10^-1 x 10^-9 returns 10^-10, it's because of exponential rules. If the base are same wuth each other, then just do the addition operation in the exponent like this :
10^(-1+(-9))
= 10^(-1-9)
=10^-10

3(-4+4)+5n=2n what are the steps for finding n
Answer:
1. Move the variables to one side: 3(-4+4) = -3n
2. Distribute. You will end up with 0 = -3n
3. Divide both sides by -3. n = 0
Step-by-step explanation:
Answer:
n=0
Step-by-step explanation:
3(-4+4)+5n=2n
first distribute
-12+12+5n=2n
combine like terms
5n=2n
subtract 2n on both sides
3n=0
divide by 3 on both sides
n=0/3
which is also equal to
n=0

1. Cesar invited 300 kids in the party. Only 15% of the kids did notshow up. How
many kids came to the party?
2. Rosa got 20% of an 80 item test incorrectly. How many items did she get
correctly?
3. There were 50 pupils in Grade Ill. If 28% of the pupils were absent, how many
pupils were present?
4. Out of 50 pupils, only 48 pupils joined the educational fieldtrip. What percent
joined the trip?
5. Among the 50 pupils in a Grade 6 class, 6% are left-handed. How many are left-
handed?
1.
300 x 0.15 = 45
300 - 45 = 255
255 kids came to the party
//
2.
80 x 0.20 = 16
80 - 16 = 64
She got 64 items correctly
//
3.
50 x 0.28 = 14
50 - 14 = 36
36 pupils were present
//
4.
48 / 50 = 0.96
0.96 x 100 = 96.0%
96% joined the trip
//
5.
50 x 0.06 = 3
3 pupils are left handed
Five less than twice the value of a number is equal to three times the quantity of
four more than one-half the number. What is the
number?
a. Let x be the number. Write and solve an equation to find x. Show your work.
b. Does the solution of your equation solve the original problem? Explain.
Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
check
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63
